C++ program: Check whether the given character is upper or lower case or not

In this article, we will discuss the concept of C++ program: Check whether the given character is upper or lower case or not

In this post, we are going to learn how to write a program to check whether given character is Upper case or lower case or not using if else in C++ language

Code to find given character is Upper or Lower or not

Code to find given character Upper or Lower or not, using if statements

In this code, we are going to learn how to check the given character is Upper case or lower case or not using if else statements in C++ language

Program 1

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    char ch;//declare character variable
    cout<<"Enter a character: ";
    //Ask input from the user
     cin>>ch;//reading the input
     if(ch>='A' && ch<='Z'){//check upper case letter
  cout<<ch<<" is an upper case letter ";
}
else if(ch>='a' && ch<='z'){//check lower case letter
  cout<<ch<<" is a lower case letter ";
}
else{//Display if it is not in Alphabets
  cout<<ch<<" is not an Alphabets ";
}
getch();
    return 0;
}

When the above code is executed, it produces the following result

Case 1

Enter a character: n
n is a lower case letter

Case 2

Enter a character: C
C is an upper case letter

Case 3

Enter a character: *
* is not an Alphabet

Code to find given character Upper or Lower or not, using Ascii

In this code, we are going to learn how to check the given character is Upper case or lower case or not using Ascii value in C++ language

Program 2

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    char ch;//declare character variable
    cout<<"Enter a character: ";
    //Ask input from the user
     cin>>ch;//reading the input
     if(ch>=65 && ch<=90){//check upper case letter
  cout<<ch<<" is an upper case letter ";
}
else if(ch>=97 && ch<=122){//check lower case letter
  cout<<ch<<" is a lower case letter ";
}
else{//Display if it is not in Alphabets
  cout<<ch<<" is not an Alphabets ";
}
getch();
    return 0;
}

When the above code is executed, it produces the following result

Case 1

Enter a character: A
A is an upper case letter

Case 2

Enter a character: n
n is an lower case letter

Case 3

Enter a character: *
* is not an Alphabet
